In addition to the ubiquitous ORA books (really, did anyone ever understand Sendmail config files before the bat book?) there were also a lot of print-outs. Huge swaths of code printed on 132-col fanfold paper. You might have a backup copy of the source code on tape somewhere, but nothing made you feel secure like having a copy of the previous working version printed out and stashed somewhere on your desk or in a drawer.
Lots of coding was done on those printouts also - you'd print out your function or your program and sit back and mark it up - especially if you were discussing or working with someone. Screens were small back then!
